Default Downy mildew on impatiens and jewelweed

Most of us here don't usually plant non-native annuals but here's a heads-up on a disease outbreak on Impatiens, both the non-native annual Impatiens walleriana and Impatiens capensis, our native jewelweed.

Anyone growing jewelweed should be aware of this disease and never plant annual Impatiens in their gardens. Hopefully your neighbors won't either but it wouldn't hurt to educate them about the problem.

I found out about this disease last year. I use to plant impatiens in my front box wood knot garden. They did great and then three or four years ago nothing but little stems. I thought I was not holding my mouth right when I planted them, or did not say a prayer over them, or give them a kiss once a week..

Now why did I not even think about it being a disease?
